In computing, a secure environment is any system which implements the controlled storage and use of information. In the event of computing data loss, a secure environment is used to protect personal or confidential data. It may also be known as a trusted execution environment (TEE).^[1][2]

Often, secure environments employ cryptography as a means to protect information. This is typically used for processing confidential or restricted information.^[3]

Some secure environments employ cryptographic hashing, simply to verify that the information has not been altered since it was last modified.
